Problems solved by technology

The operation of the above-mentioned transfer process is likely to bring secondary pollution, and also increases the burden of operation
[0004] Therefore, existing various types of fixed-depth samplers have the disadvantages of excessive empty weight and overall volume, inconvenient transportation and operation, easy to suffer from secondary pollution when transferring internal water samples, and complicated operations.

Abstract

The invention provides a water quality sampler. The water quality sampler comprises a bracket and a sampler body, wherein the sampler body is movably connected to the bracket, a sampling bag suspendedto the bracket is arranged at the upper part of the sampler body, a sampling pipe is arranged at the bottom of the sampling bag, a sinking pump is arranged the sampler body, the sampling pipe penetrates through the sampler body and is connected with a water outlet end of the sinking pump, a second sampling pipe penetrating through the sampler body is arranged at a water inlet end of the sinking pump, a water outlet pipe is arranged at the upper part of the sampling bag, a first valve one-way valve which only has a water outlet function is arranged on the water outlet pipe, a water inlet pipecommunicated with the sampling pipe is arranged at the bottom of the sampling bag, and a second valve one-way valve which only has a water inlet function is arranged on the water inlet pipe; and the sampling bag is provided with an inner bag and an outer bag, the inner bag is manufactured from tin foil when being used for collecting an organic water sample and is made from plastic when being usedfor collecting an inorganic water sample, and the outer bag is made from plastic.

Description

technical field [0001] The invention relates to the field of water quality sampling, in particular to a water quality sampler. Background technique [0002] In the known technology, all kinds of fixed-depth samplers used for water quality sampling mostly have a rigid cavity container placed below the water surface as a water storage device for sampling water at a specified depth. It occupies a large volume, which is not conducive to transportation. Avoid flooding the reservoir due to the need to keep the sampler until it reaches the specified depth. Therefore, the water storage is always full of air until the specified depth is reached, and only when the sampler reaches the specified depth, the water storage starts to exhaust and enter water. Therefore, it is necessary to counterweight the whole sampler so that its total weight in the air exceeds the weight of water equivalent to the volume of the water tank, so as to overcome the buoyancy and enter the water. As a result...
